Product Description
High Quality CH4 detection alarming device with competitive price
JCB4Portable methane detection alarming device, it is a kind of technology by single chip microcomputer intelligent instrument. Completely according to AQ6207-2007 portable carrier catalytic methane detection alarming device, design and production. Mainly used in portable monitoring of coal mine methane gas concentration in the workplace.
Alarming device adopts the natural diffusion sampling method.
Alarming device using three digital tube, expressed as a percentage volume concentration measurements, the resolution not less than 0.01% of CH4, using digital tube display value point representation of positive and negative.
Alarming device display without the single chip microcomputer artificial adjustment, can show the methane concentration below 0.1% CH4.
With sound and light alarm is alarming device self-checking function and emergency alarm, battery voltage.
On methane concentrations over measurement range limit, alarming device has the function of protecting carrier catalytic element and are keeping the alarming device display value transfinite state
Alarming device of the battery has no "memory effect" of nimh batteries.
Alarming device with a power supply voltage display, under-voltage hint, under-voltage automatic shutdown function.
Technical parameters:
Measuring range:0.00~4.00 %CH4
basic error:
0.00~1.00 %CH4 ±0.10%CH4
1.00~3.00%CH4 ±10%
3.00~4.00%CH4 ±0.30%CH4
Alarming device battery normal charge after the working hours are not less than 12 h.
Response time (T90) alarming device's response time is not more than 20 s.
Alarm function
Alarming device can be within the scope of CH4 0.50% ~ 0.50% CH4 and arbitrarily set the emergency alarm and alarm display value and the value of the error is not more than plus or minus 0.05% CH4. .
Alarming device sound intensity from the 1 m distance not less than 75 db (A); Optical signal visibility of not less than 20 m in the dark.
